Page 3: Introduction
1.0 Introduction Thank you for selecting a SunPumps SCS series solar pump system. The SCS series pump and PCA series pump controller are the key components to high quality solar powered pumping systems. Their stand-alone, pollution free and low noise operation makes them an ideal solution for remote homes, wildlife and stock watering problems without violating the environment. -
Page 4: Application
DC motor as well as various peripheral pump system signal devices. No other applications or DC power sources are recommended or warranted unless written approval is provided by the SunPumps factory. 3.0 Installation and Operation The following sections are outlined in a step-by-step format to guide you through the installation and configuration of an SCS series pump and PCA series controller. -

This splice must be watertight. Improper sealing of the splice will cause poor pump performance and may cause damage to the system. A SunPumps splice kit S-703 is recommended for this watertight connection. Never rest the pump on the bottom of the well (bore hole). This can cause the pump to fill with mud and damage the impellers. -
Page 6: Pump Installation
3.4 Pump Installation The well should be clean and disinfected before the pump is installed. You should always develop the well before installing the pump. Write the pump and controller model number and serial number in the space provided on the last page in this Instruction Manual. - Page 7 Figure 1 System Installation Layout...

Page 8: Wiring
Ensure the wire sizes are of adequate diameter (gauge) to minimize voltage drop. Please refer to a DC voltage loss table or call your SunPumps dealer for assistance. All other system equipment should be installed before proceeding with wiring the controller. Pre-configure the controller switches prior to wiring. - Page 9 Switch the controller to the OFF position. Connect ground rod conductor to the controller chassis ground block. Connect solar module frame ground conductor to controller chassis ground block. Connect pump ground conductor to controller chassis ground block. Connect pump motor negative (-), black conductor to controller terminal labeled “LD-”. Connect pump motor positive (+), red conductor to controller terminal labeled “LD+”.

Page 13: Remote Switch
3.6 Auxiliary Control Circuits The PCA-60-M1 controllers feature remote peripheral interface functions with easy programming. The remote switch interface supports float switches (storage tank level), pressure switches or a remote system “ON/OFF” toggle switch. Use only “Shielded Wire” to run from the remote switch to the controller. Induced voltages from lightning storms or two-way radio transmissions could damage the controller. -
Page 14: Adjustment Procedures
Adjustment Procedures The PCA–60-M1 controllers have several adjustment features. One feature includes system configuration adjustments, which are user selectable by a six position DIP switch located on the face of the controller. Also included are three pre-adjusted solar panel and battery selections, remote switch logic selection, low water level cut-off and electronic circuit breaker reset selection. -
Page 15: Output Voltage Adjustment
Output Voltage Adjustment The purpose of this procedure is to adjust the output voltage of the controller to reduce the water flow of the pump. Typically this is only used for low producing wells where the pump output is matched to the production rate of the well. -
Page 16: Troubleshooting
Troubleshooting PUMP DOES NOT RUN 1. Check wiring diagram for proper connections. Confirm all electrical terminations are tight and secure. 2. Check for proper voltage selector switch settings on your DC source input. If the incoming voltage is less than the set point voltage, the controller will not turn on. Two series panels should be set on switch #1, three series panels on switch #2 and four series panels on switch #3. -
Page 17: Technical Specifications
EXCESSIVE CURRENT DRAW (More than the rating of the pump, but less than the rating of the controller) 1. Check wiring diagram for proper connection. 2. Check for skinned wires or faulty underwater splice. 3. Check for locked motor armature. With the pump out of the well, bypass the controller and connect power directly to the motor leads. -
Page 18: Warranty Statement
(18) months from the date of manufacture. At its option, SunPumps will repair or replace any SunPumps product, which has failed due to a defect in material or workmanship during this warranty period. A PCA series controller must be installed in conjunction with the pump to validate the warranty.
